ZWSTECHNOTE: Error EQQDF08E DB FILLER TASK EXCEPTION: CONNECTION CLOSED BY FEDERATOR. INVALID_TOKEN CONTEXT

Troubleshooting


Problem

Starting the IzWS controller using the mirroring feature could be possible, after changing some parameters in the DWC configuration,  you could see this message in the controller's EQQMLOG:

EQQDF08E DB FILLER TASK EXCEPTION: CONNECTION CLOSED BY FEDERATOR. INVALID_TOKEN CONTEXT:
EQQDF08E DBFILLER_RES_CONNECTION

Symptom

Controller can't send data to the Federator

Resolving The Problem

JWT token coming from the Federator is saved into the EQQAD VSAM dataset, so if the DWC configuration was changed a new token is send to the controller, for realign the controller and the Federator run the modify command:

  • /F subyst,MIRRCLN
    where subsyst is the controller,MIRRCLN

  • Start the db filler by issuing the command: /F subsyst,S=DBF
